SPECIFICATION forming part of Letters Patent N 0. 693,666, datedFebruary 18, 1902. Application filed May 18,1899. $eria1ll'o. 717,292.(No model.)

To aZZ 1072,0722, it may concern.-

Be it known that 1, WILLIAM N. PARKES, a citizen of the United States ofAmerica, residing at New York, borough of Brooklyn, county of Kings, andState of New York, have invented certain new and useful Improvements inAutomatic Embroidery or Ornamental-Stitch Sewing-Machines, of which thefollowing is a specification.

My invention has special reference to embroidery, ornamental-stitch, orquilting sewing-machines.

The main object of my present invention is to improve and enlarge thescope of my former machine patented June 26, 1900, No. 652,326.

In the drawings, Figure l is a front elevation of the machine. Fig. 2 isa rear elevation of the same. Fig. 3 is a top plan view of thework-carrier-actuating mechanism. Fig. i is a front View of theactuating-ratchet for the work carrier mechanism, showing the cross-headand adjustable crank-pin connection for the same. Fig. 5 is a rear Viewof the same ratchet, showing the friction device and the arrangement ofthe actuating-pawls with one of them held out of engagement with thewheel. Fig. 6 illustrates the two pawls in engagement with the wheel.Fig. 7 is a vertical section on line a a, Fig. 3. Fig. 8 is a verticalsection on line 5 2, Fig. 3. Fig. 9 is a view of the traveler d lookingfrom left to right. Fig. 10 is a detail showing the adjustment of thecam for reciprocating the work-carrier. Fig. 11 illustrates an outlinestitched on the machine. Figs. 12, l3, l4, and 15 also illustrateoutlines stitched on the ma chine. Fig. 16 is a section online a: m,Fig. 3. Fig. 16 is a detail showing the notch b in the hoop 5 In thedrawings similar letters of reference designate corresponding parts.

Referring to the drawings, the letter A designates the bed plate, A theoverhanging arm, A the needlebar gate, A the upper shaft, and A thelower shaft, of the machine. The'needle bar movement is the same asshown and claimed by me in United States Patent granted to me October26, 1897, No. 592,510; but, as will be seen, the mechanism for producingit is different. The needlethread-loop-engaging mechanism I use is awell-known type that is used in ovcrseamingmachines.

The mechanism for holding and moving the Work preferably consists of thefollowing: In suitable guideways on the bed A of the machine is mountedand adapted to reciprocate a frame B. On the frame B is mounted andadapted to rotate an annular work-carrier rack b, on the periphery ofwhich is formed a toothed flange Z), which is adapted to be engaged by agear-wheel.. Around the inside of the rack b and at the bottom of sameis formed a flange b on which rest workholding hoops. 5 A spring 12normally presses down in a notch b formed in the workholding hoops b Ascrew b has a seat in the frame B, through which it is adapted to passand come into contact with the bed A of the machine. This screw 12serves to hold the frame B in a fixed position when movement of it isnot desired.

I will now describe the preferred means provided for rotating thework-carrier and for givingit its primary reciprocating movement.

As will be seen later on in this specification, other means are providedfor reciprocatin g the work-carrier simultaneously with the means aboutto be described or separately from the said means.

A ratchet-wheel C, Fig. 8, having a downwardly-projecting sleeve 0, ismounted on a hub 0 which has a seat in the frame B. On the under side ofthe ratchet-wheel O is adjustably attached a cam a which is adapted toengage a toothed rack 0 between the jaws 0 which are attachedtransversely thereto and extending upwardly therefrom, the rack 0 beingconstructed to slide in a suitable guideway formed in the bed Aof themachine. Keyed on the lower end of the sleeve 0 is a gear-wheel 0 whichmeshes with a gearwheel 0 mounted on a bracket 0 The bracket 0 is adjustably attached to the frame B. The gear-wheel c meshes with thetoothed annular rack b. A pawl-lever c is mounted on the upper end ofthe hub 0 A pawl c is mounted on the pawl-lever and adapted to engagethe ratchet-wheel O. A bolt 0 pass- I adapted to engage a ratchet-wheele ing through a shoe 0, and a slot 0 formed in the rack 0 serve torigidly fasten the rack when it is desired to do so to the bed A of themachine, or when it is not desired to fasten the rack c to the bed ofthe machine to retain it in its guideway formed in the bed of themachine.

.A shaft D is mounted and adapted to oscillate in standards d, fastenedin the bed of the machine. A feather d is formed longitudinally on theshaft D. A traveler d is mounted on said shaft and adapted to slidelongitudinally of the same, a way d adapted to fit the feather (1 beingformed in the traveler. An arm d extends downwardly from the traveler 66A link 01 is operatively connected at one of its ends to the arm (1 andat its other end to the pawl-lever c. A bracket 01 is attached to andcarried by the frame B. A stud d has a seat in and is carried by thebracket 61, the upper end of the stud being adapted and formed to fit ina groove 01 in the traveler d and serving to move the travelerlongitudinal of the shaft D when the frame B is reciprocated. An arm dis mounted on the rear end of the shaft D. To the upper end of the arm61 is attached a link 01 which at its other end is adjustably attachedto an upright vibratinglever d. The lever d is vibrated in a usualmanner from a cam (not shown) which is mounted on the under shaft of themachine.

The following serves as a means for turning the ratchet-wheel C aroundmanually and through it setting the work-carrier ahead or backward ameasured distance or changing a predetermined number of teeth theangular position of the said ratchet-wheel C and the mechanismoperatedby it with respect to the angular position of the ratchet-wheelZ and the. mechanism operated by it. On a stud E is mounted a hand-levere, on the upper side of which is mounted a pawl 6 which is Theratchet-wheel e is attached to the upper side of the ratchet-wheel 0,its teeth slanting in the opposite direction tothose on the ratchetwheel0, as shown in Fig. 3. A spring 8' nor mally tends to hold the pawl e inengagement with the ratchet-wheel C, and pin 6 serves as a means forholding the said pawl out of engagement with the teeth of the saidratchet-wheel O. The pin 6 fits in an ordinary pin-hole, from which itis readily removed to allow the pawl e to engage the ratchet-wheel 6when it is desired to reverse the said wheel. A spring (2 serves tonormally hold the outer end of the lever e against the stop-pin e and ascrew 6 passing horizontally through a stud 6 serves as a means foradjusting the stroke of the lever e", and through it the pawl 6 Astop-pawl 6 mounted on the under side of the lever e, is adapted toprevent retrograde movement of the ratchet-wheel C. An ordinarycatchspring 8, having a downwardly-extending eoaeee portion (not shown)is provided for holding the pawl out of engagement with the ratchetwheel0 when it is desired to reverse the same. An adjustable friction-strap eencircles a flange formed on the under side of the ratchet-wheel 6 Aspring 6 attached at one end to a projecting part of the friction-strapand at the other end to a pin 6 normally draws on the ratchet-wheel O inthe opposite direction to the rotation of the same and prevents anyundesirable forward movement. A catch-spring e is adapted to hold thepawl 0 out of engagement with the ratchetwheel 0 when it is desired toreverse the same. A segmental toothed lever F is mounted on a stud f,the toothed portion of which is adapted to engage the teeth on the rack0 An outer end f of the lever F is formed and adapted to indicate theworking position of the work-carrier b by means of a gage f Pin-holes fin the gage f and pins f serve as means for the operator to prelo catethe working position of the work-carrier I).

I have now described mechanism adapted to rotate the ratchet-wheel G,which in turn rotates the gears c and c and they in turn rotate thework-carrier b. It is noticed that the'rotation of the ratchet-wheel Calso rotates the cam 0 which is attached to the under side of the same.Assuming that the rack e is rigidly held to the bed of the machine, itis further seen that the rotation of the cam 0 through its engagementbetween the jaws o reciprocates the frame B, and through it thework-carrier b. The extent of the actuating movement of the cam 0' willof course determine the extent of the reciprocations of thework-carrier, and the extent of this movement is under adjustment, asshown in Fig. 10. It is seen that the number of reciprocations of thework carrier with respect to the number of rotations of the same dependson the size of the gear-wheel 0 It is also seen that the extent of thestroke of the actuating-pawl 0 determines the number of stitches thatwill be made during the complete rotation of the work-carrier b.

To partly explain the workings of the workcarrier up to this point, wewill assume that the adjustments for the proper length of stitch hasbeen made and that we desire to simply stitch a circle. To accomplishthis, the screw 0 is loosened and the screw b is tightened sufficientlyto prevent any movement of the frame B. Under these circumstances,assuming that the segmental toothed lever B is out of actuatingengagement with the rack c, if the machine is actuated the rack 0 willreciprocate, and the work-carrier will simply rotate, and thus stitch ina circle. If it is desired to stitch a number of concentric circles, thescrew b is loosened and the position of the work-carrier adjustedlaterally for each circle. If it is desired to stitch a circle ofscallops, the screw Z) is ICO ' loosened and the screw tightened, whichprevents movement of the rack 0 The frame B, being now free to move, iswhen the cam O is rotated reciprocated, and through it the work-carrieris reciprocated, and as it is rotated at the same time of course theoutline stitched will be a circle of scallops. The number of scallops ina circle depends on the number of times the cam c revolves with respecttothe rotation of the work-carrier b. An unlimited number of designs canbe stitched through the mechanism thus far described by changing thesize of the gear 0 or the shape of the cam 0 For example, if the cam cis constructed and actuated so as to reciprocate the work-carrier fourtimes during a complete rotation of the carrier it is evident thatfigures having square outlines will be stitched and that the shape ofthe cam and the extent of the action of the same will determine thedetail outlines of the figure.

Before passing to a description of the balance of the mechanism providedfor the movement of the work I will describe the mechanism provided formoving the needle-bar laterally or producing a relative jogging movementbetween the needle and the work-carrier. In United States Patent No.592,510, granted to me October 26, 1897, before mentioned, I show anddescribe a number of then new needle-bar movements. In my presentinvention, which is the subject of this application, I use the sameneedle-bar movement described in the above-referred-to patent, but useimproved mechanism for producing it.

On the front side of the arm A of the machine I attach a plate G,onwhich my mechanism controlling the lateral movements of the needle-baris mounted. On the shaft A of the machine is mounted a beveled gear g,and mounted in a suitable bearing on the arm A of the machine is abeveled gear g which meshes with beveled gear g. A shaft g is formed onthe beveled gear g which extends outwardly through the bearing for thesame. On the outer end of the shaft g is attached a disk g*, in which isformed a slot 9 A link 9 is at one end adjustably connected in the slotg and at the other end connected to a pawl-lever g on which is mounted apawl 9 The pawl g is adapted to engage a ratchetwheel g, on the back ofwhich is attached a cam g (shown in dotted outline,) which engages aslide 9, mounted in guideways 9 through friction-rollers 9 which aresnitably mounted thereon. To the forward end of the slide g isoperatively connected the lower end of a lever g, which is mounted on anadjustable fulcrum g. A bell-crank lever II is mounted on the plate G'ath, the lower member h of which is engagement with a usual switch-cam,(such as is used in overseamingmachines,) which is mounted on the uppershaft of the machine. In the horizontal member of the bell-crank lever His a groove 7L2, in which ashoe ha is adapted to slide, a plate 7t",

same and the said lever h.

in which there is a slot 7L5, serving to retain the shoe in the groove72/ A link 71 is attached at its lower end to the shoe 71, and at itsupper end to the horizontal member of a bell-crank lever 7L7, which isadapted to be fulcrumed on the upperend of the lever 9 or the plate G. Alink 7L is at one end attached to the vertical member of the bell cranklever h and at its other end to the needle-bar frame A To the rear endof the slide 9 is attached a lever h, which is adjustably fulcrumed onthe plate G. A link It is at one end adapted to be connected to theplate G or the lever h". It will now be seen that if the lever h7 isfulcrumed on the plate G an ordinary vibrating movement can be given tothe needle-bar and that the extent of this movement can be regulatedthrough the adjustable connection of the link it to the plate Gr. It isalso seen that by connecting the link h with the lever h the extent ofthe vibratory action of the needle can be automatically increased ordecreased through the action of the ratchet-wheel g and the intermediatemechanism between the It will also be observed that by adjusting thebell-crank lever h to the lever the working position ofthe lateralvibration of the needle-bar will be changed under the action of theratchet-wheel g slide 9, and the lever-g. It is seen by referring to thedrawings that all of these movements are under adjustment and that bychanging the adjustments a large variety of different lateral movementscan be given to the needle-bar and through ita large number of differentstitches produced.

I will now describe the means which are preferably provided for bodilymoving the work-carrier and its primary operating mech anism laterally.The mechanism I have pre= viously described for rotating the work-car'-rier and moving it laterally produces anniform relative movement betweenthe carrier and the needle-'-that is to say, during one rotation of theratchet-wheel O and the cam carried by it the work-carrieris given arotary movement of a predetermined extent and a reciprocating movementof a predetermined extent, and these movements are repeated each timethe ratchet-wheel O rotates.

The following mechanism moves the workcarrier and the mechanismpreviously described for operating it laterally without interfering withthe action of the said mechanism on the work-carrier; but'of course asthe working position of-the work-carrier is changed the movement of thesaid work-carrier relative to the needle from the action of the saidmechanism is automatically changed or varied.

To a hub on the forward end of a shaft L is attached a disk Z, theperiphery of which is mounted in the bearing Z The rear end of the shaftL is mounted in a standard Z which is attached to the bed A of themachine.

On the shaft L, next to the disk Z, is mounted one end of a pawl-lever ZNext to the pawllever Z is a ratchet-wheel Ziwhich is mounted to turn onthe shaft L. On the ratchet-wheel Z is formed a hub Z6, on the end ofwhich is fastened a gear-wheel Z On the side of the ratchet-wheel isattached a flange Z encircled by a friction-strap Z In the upper end ofthe standard Z is rigidly secured a stud Z on the outer end of which ismounted to turn a gear-wheel l ,Which meshes with gear-wheel Z On a hubZ formed on the gear-wheel Z, is rigidly mounted a gear-wheel Z whichmeshes with a gear-Wheel l flwhich is mounted on the shaft L and rigidlyheld to the same by means of set-screws. A crank-pin Z is adj ustablyconnected by means of a shoe in a keyway Z which is formed in the faceof the disk Z. On the outer end of the crank-pin Z is mounted a shoe 1".On the upper end of the pawl-lever Z are mounted pawls'l and Z.

A pin Z projects upwardly from the pawl Z A catch-spring Z is adapted tohold the pawl Z out of engagement with the ratchet-wheel Z Theupwardly-extending pin Z enables the operator to readily adjust the pawlZ out of engagement with the ratchet-wheel 2 as is seen in Fig. 5. Acatch-spring Z is adapted to hold the pawl Z out of engagement with theratchet-wheel when the pawl is lifted high enough to be caught by thesaid catch-spring. Springs Z serve to normally hold the pawls Z and Zinto engagement with the ratchetwheel 1 A stop-pawl Z serves to preventany undesirable rearward movements of the ratchet-wheel Z A spring Z oneend of which is attached to a fixed pin and the other end to thefriction-strap Z and drawing on the same in the opposite direction tothe rotation of the ratchet-Wheel Z serves to prevent any undesirableforward movement of the same.

It will be observed that the object of the train of back-gearing is togive a wide range of action of the ratchet-Wheel Z on the shaft L, andusing two actuating-pawls is also for the same object. its outer end soas to move the actuatingpawls the distance of one-half of a tooth of theratchet-wheel Z and both of the pawls are in engagement with the same,it is seen that it will take two strokes of the lever to move theratchet-wheel ahead one tooth. Of course the same object could beaccomplished by having more teeth on the wheel; but this would make itnecessary to have an undesirably-large wheel or undersirably-small teethon the same. A link Z at one end connected with the pawl-lever Z and atits other end adjustably connected to the lever d,

serves as a means for transmitting the vibrations of the lever 61 to thepawl-lever Z. A cross-head Z is in engagement with the shoe Z. Anextension Z at the rear end of the cross-head and a toothed rack Z whichis attached to a forward extension Z of the same, are adapted toreciprocate in guideways Z If the lever l is moved at portion of therack Z Screws f passing through slots f in the gear f and having seatsin the segmental toothed lever F, serve as means for adjustablyfastening the gear f to the segmental tooth-rack F.

It is seen from the foregoing that the workcarrier is reciprocated fromthe movement of the ratchet-wheel O and the cam or eccentric which iscarried by it. This cam operates between jaws, as before stated, whichare attached to or formed on the rack c". When the ratchet-wheel O isrotated, the frame B is reciprocated with respect to the rack o theextent of the action of the cam which is carried by the saidratchet-wheel, so that the movement of the frame B with respect to therack 0 remains of a uniform extent. This extent, as before pointed out,is determined by the adjustment of the cam on the -ratchet-wheel. If therack c" is held in a stationary position, then the movement of thework-carrier through the action of the said ratchet-wheel and cam willbe uniform with respect to needle; but if the said rack c is moved orshifted during the movement of the said ratchet-wheel and cam itisobvious that the movement of the work-carrier relative to the needlewill be varied. The rack c is moved, as has been described, from theaction of the ratchet-wheel C and the mechanism intermediate the sameand the said rack, and as the position of the rack determines theworking position of the work-carrier the latter is of courseautomatically changed when the position of the rack is changed.

As the frame B is moved from the movement of the ratchet-wheel O and theintermediate mechanism between the same and the said frame and as aplurality of stitches and a plurality of movements are made during themovement of the frame in one direction, or, as in the present example ofmy invention, during one half of a rotation of the ratchet-wheel O andis then moved in an opposite direction during the other half of therotation of the said ratchet-wheel, it is seen that'this is aprogressive or step-by-step movement.

The backward and forward movements of the frame 13 from theratchet-wheel O are of a uniform extent as between the said frame andthe rack 0 but as the latter is bodily moved through the action oftheratchetwheel Z and the mechanism between the same and the said rackit is seen that the movement of the frame B from the movement of theratchet O and through it of the work-carrier with respect to the needleis automatically varied. This is assuming, of course, that the movementsof the rack c from the ratchet Z differ as to speed or direction orextent from the movement produced on the work-carrier by theratchet-wheel O and the cam carried by it.

In practice, as in the present case, the

and Z A gear f meshes with the toothed I ratchet moves the rack 0through a train of gears and a rack between the same and the.

ratchet-wheel O and the gearing between thesame and the rack, and thesaid rack gets a progressive movement in one direction and then in anopposite direction from the movement of the frame 13 through the saidratchetwheel 0 and the cam 0 and this second pro-- gressive movement ofthe work-carrier rack 19 is automatically varied from the movement ofthe ratchet-wheel Z and the mechanism between the rack and the saidwork-carrier rack 1).

Referring to the figures showing some outlines stitched on the machine,Fig. 11 shows an outline stitched through the action of theratchet-wheel Z and its intermediate connections with the work-carrier,the cam 0 having been moved to a central position, so that thework-carrier receives no action from the same. Under these circumstancesthe work-carrier is simply rotated through the action of theratchet-wheel O and the intermediate gearing between it and theworkcarrier. To stitch the square outline shown in the before-mentionedFig. 11, the stroke of the actuatingpawl for actuating the ratchet Z ismade of such an extent that the disk Z is rotated four times while thework-carrier rotates once. The adjustment of the crank-pin Z toward thecenter or from the center of the disk Z and the distance from the centerof the workcarrier of the needle determines the convexity or concavityof the sides of the square outline stitched. Of course by adjusting thecrank-pin Z the proper extent from the center of the disk Z the sides01": the outline stitched will be straight. Outline shown in Fig. 12 isproduced by reciprocating the work-carrier eight times (While it isrotated once) through the action of the ratchet-wheel O and mechanismintermediate the same and the work-carrier. The outlines shown in Figs.14: and 15 are modifications of the action produced by changing theworking position of the reciprocating work-carrier through the action ofthe ratchet-wheel Z and its mechanism. Of course to produce thesefigures the angular position of the crank-pin Z relative to the angularposition of the cam c has to be properly adjusted. The difference in theoutline of these two Figs. lat and 15 is produced by changing theangular position of the cam c and the crank-pin Z relative to eachother, the extent of the stroke of the actuating-pawls being the same.The oval shown in Fig. 13 is produced by reciprocating the work-carrieronce to one rotation of the same. The small action shown on the edge ofthe outlines is produced by the action of the needle-bar.

The needlebar is vibrated by one cam. The amount of this vibration isautomatically increased and decreased and the working position of thisaction is changed laterally. The Work-carrier is rotated through theaction of a ratchetwheel, is reciprocated by the action of a cam, andthe working position of this action is changed laterally by the actionof a crankpin adjustably attached to a rotating disk.

All of these actions can be used individually or collectively, and theyare all individually adjustable with respect to each other.

It is of course seen that an endless variety of designs can beautomatically stitched on this machine, that by changing the angularpositions of the ratchet-wheel O, Z and 9 relative to each other, andthrough them the cams they actuate, varies the design stitched; also,that the numberot times these ratchetwheels turn relative to each otherand also the number of times they turn relative to the number ofstitches made by the stitching mechanism varies the pattern.

I do not wish to be confined to the particular form and arrangement ofparts herein disclosed, it being understood, of course, that variouschanges might be made in the same which would produce the same orsimilar results.

The size of material that can be operated upon is limited by the size ofthe work-carrier and the machine. WVhen it is desired to use the machinefor quilting or embroidering on large pieces of work, the carrier forholding the work and the machine and the mechanism operating the carriercan be enlarged sufficiently for said purpose.

In the preferred form of the invention herein disclosed I have shown astitch-forming mechanism comprising a single needle. It is obvious,however, that a stitch-forming mechanism comprising a plurality ofneedles might be used.

The combination with asewing-machine having stitch -forming mechanism, of feed mechanismcomprising a rotating work-carrier adapted to be reciprocated, means forreciprocating the said work-carrier, a ratchetwheel and means foroperating the same, and means comprising a train of gearing intermediatethe ratchet-wheel and the work-carrier whereby the reciprocatingposition of the work-carrier is automatically changed.

16. In a sewing-machine,a needle and means for reciprocating it, awork-carrier, means for operating the work-carrier so as to move thework in a plane substantially at right angles to the plane in which theneedle reciprocates, means for producing a relative vibrating or joggingmovement between the needle and the work-carrierl'means for producing arelative progressive step-by-step movement between the'needle and thework-carrier, and means for simultaneously varying the amplitude of thesaid relative jogging movement and the amplitude of the steps of thesaid relative progressive movement.

17. In a sewing-machine, a vertically-reciprocating andlaterally-vibrating needle bar or holder, a needle carried by the saidneedlebar, a work-carrier, means for operating the said work-carrier soas to move the work substantially at right angles to the lateralmovements of the needle, means for reciprocating the work-carriersubstantially in the same direction in which the needle moves laterally,and means for automatically varying the amplitude of the saidreciprocation of the workcarrier.

18. In asewing-machine,a needle and means for operating it, aWork-carrier, means for producing a relative rotary movement between theneedle and the Work-carrier, an oscillating shaft, a device operatedfrom the movement of the said shaft for producinga relativereciprocating movement between the needle and the work-carrier, andmeans for automatically moving the said device laterally and therebyvarying the amplitude of the reciprocating movement between the needleand the work-carrier.

19. In a sewing-machine,a needle and means for operating it, awork-carrier mounted and adapted to be reciprocated and rotated in ahorizontal plane, a shaft extending in a horizontal plane and adapted tooscillate in a vertical plane, a traveler mounted and adapted to move ina horizontal plane and in the same direction in which the work-carrieris adapted to reciprocate, moans intermediate the traveler and theWork-carrier whereby when the aforesaid shaft is oscillated thework-carrier and traveler are reciprocated, and means for oscillatingthe aforesaid shaft.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
